When considered from a quiet seashore, the sea, with its rolling waves and titanic expanse, can look calm, even serene. yet hidden underneath the sea’s waves are a remarkable abundance and diversity of energetic creatures, engaged within the unending struggles of life—to reproduce, to consume, and to prevent being eaten.
With Sex, medications, and Sea Slime, marine scientist Ellen Prager takes us deep into the ocean to introduce an mind-blowing solid of attention-grabbing and weird creatures that make the salty depths their domestic. From the tiny yet voracious arrow worms whose rapacious methods could lead to demise via overeating, to the lobsters that conflict competitors or seduce associates with their urine, to the sea’s masters of conceal, the octopuses, Prager not just brings to existence the ocean’s unfamiliar beings, but in addition finds the methods they have interaction as predators, prey, or power associates. And whereas those animals make for a few jaw-dropping stories—witness the ocean cucumber, which ejects its personal intestines to confuse predators, or the hagfish that ties itself right into a knot to maintain from suffocating in its personal slime—there’s way more to Prager’s account than her ever-entertaining anecdotes: time and again, she illustrates the the most important connections among existence within the ocean and humankind, in every thing from our nutrients offer to our financial system, and in drug discovery, biomedical learn, and renowned culture.
Written with a diver’s love of the sea, a novelist’s ability at storytelling, and a scientist’s deep wisdom, Sex, medicinal drugs, and Sea Slime enchants because it educates, spell binding us with the wealth of existence within the sea—and reminding us of the necessity to guard it.

Observable adjustments with local and international implications, similar to warming temperatures and diminished sea ice, are occurring around the Arctic. despite the fact that, the checklist of Arctic observations suffers from incomplete geographic insurance and restricted length, and measurements aren't good coordinated. This makes it tricky to comprehensively describe present stipulations within the Arctic, not to mention comprehend the alterations which are underway or their connections to the remainder of the Earth procedure.
Alien Ocean immerses readers in worlds being newly explored by means of marine biologists, worlds often out of sight and achieve: the deep sea, the microscopic realm, and oceans past nationwide limitations. operating along scientists at sea and in labs in Monterey Bay, Hawai'i, the Woods gap Oceanographic establishment, and the Sargasso Sea and at undersea volcanoes within the japanese Pacific, Stefan Helmreich charts how revolutions in genomics, bioinformatics, and distant sensing have pressed marine biologists to determine the ocean as lively via its smallest population: marine microbes.

That’s right, the hagfish. Scientists are very interested in their primitive immune 30 C h a p t e r t w o systems, which have long protected them against infection. It is especially intriguing given the hagfishes’ propensity to feed on the dead, which are usually laden with bacteria and other microbes. Researchers have already identified three potent, broad-spectrum antimicrobial compounds in the Atlantic hagfish that might help to explain their ability to ward off microbial diseases. Hagfishes have also been found to get liver cancers and may provide a means to monitor carcinogenic pollutants in the marine environment.
5 meters (5 feet) away. Lobsters actively sniff for undersea “odors” or chemicals by flicking their smaller pair of antennae, or antennules, back and forth. In laboratory studies, the lobster to pee first and with the “sweetest” smelling urine, along with the largest claw, is the most likely to win in battle. ” When a female Maine lobster approaches a shelter, hot for some action, she not only sniffs for a male’s pee, she lets loose a stream of her own. Her urine can render a once brutish male docile and even touchy, feely.
